WATER-CLOSET.

To all whom it may concern.-

Be it known that I, HARRY S. MADDOCK, a citizen of the United States, residing at Tren ton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Water-Closets, of which the following is a specification.

My invention relates to that class of waterclosets which are made of earthenware, and especially to means of connecting such water-closets with the metallic pipe furnishing a supply of water to flush the bowl. Heretofore it has been common to join the supplypipe with the earthenware bowl of such watar-closets by interlocking devices constructedupon the ends of the supply-pipe or coupling-pipes therewith connected and within a recess formed in a projection upon the side of the bowl near its top, making the joint water-tight by means of washers or cement packings, or both. The objection to these joints, which are universally considered the best in existence, has been their liability to break owing to the giving way of the earthenware at the joint when strainhas been ex erted upon the supply-pipe by reason of settling of the building in which the closet was located or other causes. the earthenware at this point is due to the fact that in making the earthenware bowls of the closet the practice. has been to apply to the wall of the closet at the point of junction of the supply-pipe therewith a ring of clay molded separately from the bowl of the closet. The ware being fired, the earthenware ring is baked fast to the bowl; but the line ofjunction between the ring and the bowl isalways the point of fracture under strain of the supply-pipe, and this fracture so frequently occurs as to form a great objection to this method of construction, as such a fracture at, this point entails the purchase of an entire new closet, the expense of which is considerable.

To obviate this objection to these :joints is.

the object of my invention, and I eifect it by augmenting the wall of the bowl at the point of its juncture with the supply-pipe, thus making the entire earthenware structure integral and homogeneous.

I shall 'now proceed to describe my inven-,

tion and the method of practicing the same supply-pipe with. the bowl.

vtains the socket.

This giving way of I v is located therein.

Figure 1 represents a portion of an earthen-' ware water-closet bowl containing my improvement. Fig. 2 shows a perspectlve view of a part of the coupling-pipe connecting the side elevation of a bowl containing my invention with a portion of its wall broken away to give a sectional view of the wall at the point of junction of the supply-pipe and the bowl. Fig. 4 is a rear View of the bowl, showing the socket for the supply-pipe therein. Fig. 5 is a rear elevation of the mold in which the bowl is formed when in process of manufacture, a portion of the wall of the mold being cut away to show the formation of the inner part of the wall against which fits the removable section of the mold. Fig. 6 is the removable section of the mold, in which section is formed the projection of the bowl which con- Fig. 7 is a plan View of the top of the mold in which the bowl is formed as the mold appears when assembled; and Fig. 8 is a side elevation of the mold, showing a vertical sectional view thereof in dotted lines.

In illustrating my invention I have shown a common form of water-closet bowl andconnecting-joiut between it and the supply-pipe, and in which A is the bowl, and B that portion of the bowl in which is formed the socket to receive the end of the connecting-pipe which 0 is the supply-pipe, lead ing from the flushing-tank to the closet. D is the connecting-pipe, by which the supplypipe is attached to the bowl of the closet. E is a coupling-nut for attaching the end of the supply-pipe to one end of the connecting-pipe. F is a jam-nut. G is the washer. H is the flushing-rim. The construction and connection of this bowl and supply-pipe are so well known as hardly to need explanation here, the bowl being constructed with an aperture a, through which the water from the supplypipe flows into the flushing-rim and the bowl, and the bowl being externally provided with a socket having slots 1) b b with undercut portions, (see Figs. 1, 3, and 4,) into which is passed the end of the connecting-pipe D in such a way that the lugs c c 0 enter the slots Fig. 3 shows a bb b, and when the pipe is brought to its seat it is given aslight. turn to the left to bring these lugs in the undercut portions ofthe slots b b b,and thus prevent withdrawal of V the connecting-pipe from its socket. The intervening spacebctween the exterior of the,

connectingpipe B and the interior of the socket-opening in the bowl is preferably filled with cement, and a washer G being "passedover the end of the connecting-pipe is brought 3 closely against the flattened face of the earthenware wall, in whichthe pipe D islodged by the clamping-nut F, thus eifectingal water;

\ As has'beensaid above the method of preparing the earthenware socket for the connecting-pipe D has been such as to form adetecti've union of the earthenware at this point,

r inasmuch as the socket has been formed in 5 a separate piece of earthenware, which has been simply stuck onto the wall of the bowl, and'the firing of the ware has not operated to producea homogeneous structure at this point.. The result has been a comparativelymolds of regular forms and sizes.

' "part J has formed upon it an inwardly-'proe'asydetachment of the earthenware ring or socket fromthe bowl by reason of any force operating to withdraw the connecting-pipe fromthe bowl. To overcome this difliculty,

" Iaugmentthe wall of the bowl at the point of connection between it and the connecting: The proportions of this and supply pipes. augmentation are clearly exhibited in the drawings in Figs. 1, 3, and 4, the dotted lines in 'Fig. 3 showing the ordinary thickness of the wall of the bowl and the augmentation thereof.

ing'grooves "or slots in the underside of' the part J and serve to accurately fix and retain it-in'its'proper position during the process of molding the bowl.

The mold being assembled, the plastic clay is. placed within it,and the bowl'is molded in the usual and To effect this augmentation has been a matter of difliculty, because of the ne-:'

As it is im-, possible to form a socket such as is found in: these structures for the reception of the con-. heating-pipes in any ordinary mold from which'the bowl'when formed is withdrawn, I haveresorted to the construction for this purpose of a mold shown in Figs. 5, 6, 7, and; 8- of thedrawingsfin which figures I indicates.

This part J fits" we'll-known manner. When it is sufliciently "dry to be removed from the mold, it is placed upside down, and the main body of the mold I isremoved from the bowl in avertical line. This permits the part J to slide out of its place in .the, mold I,. and it remains fixed upon the side of the bowl.- The body'of the mold being removed, the part J is withdrawn from .the bowl in a horizontal direction, and the bowl is thus left completely formed, with the exception of the slight undercuts of the slots ornotches b b b, which are made in the form i udicated in Eig l by means of a small tool suitable for thepurpose. I am thus enabled to form the socket for the connecting-pipe injtegral with the bowl itself, and that portion vof the bowl is as strong as any other part thereof, and all extraordinary tendency to fracture at this point is entirely overcome.

-"It will be readily understood that the essence of my invention is the forming of the walls of the socket for the connecting-pipe integral with the bowl and that any'form of connection involving the 'j'unctionof the con meeting-pipe with the bowl at a point within walls integral with the entire bowl embodies my improvement. I do not therefore desire to be limited to the specific form of connection here shown; but
